Keenan v UK 27229/95 [2001] ECHR 242

The applicant's son had committed suicide while serving a prison sentence. Her Article 2 complaint was rejected (the authorities responded in a reasonable way to his conduct, placing him in hospital care and under watch when he evinced suicidal tendencies) but her Article 3 complaint was accepted (lack of effective monitoring and informed psychiatric input into his assessment and treatment, together with the imposition of punishments including seven days' segregation).
